XPontus XML Editor is a simple XML Editor oriented towards text editing. It can perform validation(DTD, XML Schema, Relax NG, Batch XML validation), XSL transformations(HTML, XML, PDF, SVG), schema/DTD generation, XML/DTD/HTML/XSL code completion. The brand new version is now plugin based to solve some limitation issues.
Modularity
XPontus is now built on top of a plugin framework to allow a modular development. Most of XPontus features are provided as plugins.

Code completion
For general XML files code completion is built on the fly when a DTD or schema is associated to the document. XSL completion is provided using a DTD embedded in the XML code completion plugin.

For HTML files, an embedded DTD is used to create the code completion database.

XPath support
XPath 1.0 plugin is shipped.

Syntax highlighting
Syntax coloring is enabled for XML and HTML files

XSL transformations
Like in the previous versions, XSL transformations are available(PDF, HTML, XML, SVG, TEXT).
